Fiona Red, a brilliant but quirky FBI loner, spends most of her time in the lab or at crime scenes. She comes from a family used to being around death and bodies, her parents having run a funeral parlor, and she would have run the family business if not for a tragedy in her her sister was abducted when she was a teenager, and never found.

Fiona remains determined to crack her sister’s case. But in the meantime, as an FBI agent, she applies her brilliance to catching killers and cracking cases that no one else can, as bugs are the first visitors to dead bodies.

With her FBI partner out in the field, Fiona expects to stay behind the scenes.

I love where this story is going and I can't wait to see what happens in the next book. Especially with that cliffhanger.
I'm not happy what Lauren decided to come back all of a sudden. WHY CANT SHE JUST LEAVE LIKE MARK AND LET RED AND JAKE ME HAPPY!? I also can't wait to see wheretl the story line goes for both of the cold cases that they both have in their lives. I NEED ANSWERS!

I’ll be honest, I don’t even know how I made it this far. I kept wanting to know what happened to her sister but it’s so frustrating when the only tidbit you get is in the prologue and epilogue…over it

It was a nice story but I like trying to figure out the case with the characters.I felt like an observer instead of really picking up on clues and guess who done it. Also the audio book narrator doesn't pause at scene changes and seems rushed.

Wow!

Everything was coming together, Fiona was close to getting answers, and Jake had a late night visitor that will upset their relationship. I could not put this book down. I read it in one day.

You guys… I LOVE these stories! But the proofreading (or lack thereof) is killing me… so if Blake Pierce ever happens to see this review, please contact me - I would be more than happy to proofread your next book!

scary

Great story again. Fiona a Jake make such a great team. It’s gripping and scary at the same time as they race against time to catch a killer.

the twist ending was epic!

I did not expect ANY of the last parts of the book after they caught the killer! My mind is completely blown and I cannot wait to start book 7.

This particular series by Blake Pierce about an entomologist working with the FBI isn't my favorite.
